23 Claims. 1

.The presentzinvention relates to washing apparatus, and moreparticularly to improved dishwashing' apparatus of the general characterof that disclosed in the copending application of Forrest A. Walker,Serial No. 57,448, filed Octoher-30, 1948.

The dishwashing apparatus disclosed in the Walker application mentionedis of the timed washing cycle type that performs automatically and inpredetermined sequence given. steps in cluding spraying, washing,rinsing and drying of thedishes and otherutensils contained therein.This apparatus comprises a cabinet having a front opening and housing avertically disposed vat including wall structure terminating in aforwardly directed doorway having a front opening registering with thefirst-mentioned front opening, and a door arrangedin the doorway andmounted for movements with respectto the front openings between asubstantially vertical closed position and a substantially horizontalopen position. The wall structure of the vat and the door respectivelycarry cooperating ballles and are otherwise so constructed and arrangedthat hot washing fluid or liquid circulated in the vat does not escapebetween the doorway and the door out of the front opening,notwithstanding thefact that the usual sealing gasket therebetween hasbeen omitted.

While this gasketless door and doorway construction in the apparatus ofthe Walker application is highly eflicient and positive inoperation,vapor given off by the hot washing liquid cir culated in the tank risestherein and escapes between the top of the doorway andthetop of the doorand out of the top of the front openings. This operation is not in anyway objectionable within itself, and is, in fact, very advantageous;however, the vapor rises gently adjacent to the top front of the cabinetinto contact with the front edge of the cold sink normally overlying thetop of the cabinet causing the vapor to condense thereon. The resultingcondensate collecting on the front edge of the cold sink then drips backupon the kitchen floor in a highly objectionable manner, whereby thehousewife,

without examining the circumstances closely, er-

roneously concludes that the hot washing liquid circulated in the vat isescaping from the front openings between the doorway and the door in itsclosed position. While this difficulty is encountered only when. theapparatus is positioned below! a sink or other coldi work surface, thiscombination is so. frequently: and generally" used in. modern kitchensthat the undesirable char 2 acteristic noted may be considered tobeinherent in the apparatus itself.

Accordingly, it is a general object of thepres'ent invention to providewashing apparatus of the front-opening gasketless-door type that may be.

employed below a sink or other cold work surface without producingcondensation upon, the; sink of'vapor issuing from the apparatus.

Another object of the invention is to provide in washing apparatus ofthefront opening type; an improved arrangement for projecting out of thefront opening to the exterior the vapor given off by the hot washingliquid circulated therein.

Another object of the invention is to providein washing apparatus of thefront-opening gas ketless-door type an improved arrangementforventilating the interior of the vat through thestructure of the frontdoor and thence out of the top of the front opening to the exterior.

Another object of the invention is to provide in washing apparatus of:the front-opening: gasketless-door type an improved arrangement forventingvapor from the interior of the vat and for deflecting condensateresulting from the vented? vapor back thereinto.

A further object of" the invention is to provide in washing apparatus ofthe front-opening gasketless-door type, improved structure carried bythe cabinet of the-apparatus for directing vapor out of the top of thefront opening to the exterior.

- A further object of the invention is to provide in washing apparatusof the front-opening gasketless-door type, an air blast arrangementfordirecting vapor out of the front opening to the exterior.

Still a further object of the invention is to. provide-the combinationof a sink, washing. apparatus of thefront opening type disposed belowthe-sink and characterized by theissue of vapor out of the frontopening, and an arrangement.

for projecting the vapor forwardly from. the front opening out ofcontact with the frontedge of the sink in order to prevent condensationof the vapor thereon.

Further features of the invention pertain to the particular arrangementof the elements; of the washing apparatus, whereby the above-outlinedand additional operating features thereof are attained.

Theinvention, both as to its organization. and method of operation,together with further objects and advantages thereof, will best-beunderstood byfreference-to the following specificationtaken inconnection with the accompanying drawings, in which Figure 1 is a frontelevational view, partly broken away, of dishwashing apparatus of thefront-opening gasketless-door type incorporating fixed structure fordirecting Vapor out of the top of the front opening and embodying thepresent invention; Fig. 2 is a vertical sectional view, partly brokenaway, of the dishwashing apparatus, taken in the direction of the arrowsalong the line 2-2 in Fig. 1; Fig. 3 is an enlarged fragmentary verticalsectional view of the upper front portion of the dishwashing apparatusshown in Fig. 2, illustrating in detail the structure of the top of thedoor, the vat, the cabinet and the vapor director and indicating thenormal relation of these parts with respect to the front edge and worksurface of an associated sink; Fig. 4 is a horizontal sectionalvie w,partly broken away, of the dishwashing apparatus, taken in the directionof the arrows along the offset line 4-4 in Fig. 2; Fig. 5 is afragmentary vertical sectional view of thelower front portion of thedishwashing apparatus shown in Fig. 2,'illustrating in detail thestructure of thecondensate deflecting gaskets respectively carried by,the lower portions of the front-door side flanges and by the lowerportions of the front doorway side flanges; Fig. 6 is an enlargedfragmentary vertical sectional view of the condensate deflectinggaskets, taken in the direction of the arrows along the line 6-6 in Fig.5; Fig. '7 is an enlarged plan view of the vapor director carried by theupper front portion of the cabinet; Fig. 8 is an enlarged frontelevational view of the vapor director shown inFig. '7; Fig. 9 isanenlarged'end elevational viewof theva or director shown in Figs. 7 and8;

Further, thefront wall 21 carries a front panel 35 having an opening 35 formed inthe upper portion thereof and offset toward the right-hand side thereof,the front opening 36 surrounding the front opening 34 and overlying aconsiderable marginal portion thereof adjacent to the lower portion ofthe front wall 27. The front panel 35 is provided with an inwardlydirected marginal flange 31 surrounding the front opening 36 and lyingwithin thetop and side flange structure 33. Also the front panel 35 isprovided with an inwardly directed boundary flange 38, the top and sideportions thereof being respectively disposed substantially flush withthe top wall 22 and the side walls 24 and 25, and the bottom portionthereof overlying the horizontal panel 32. More specifically, the frontpanel 35 is removably secured to the front Wall 21 by an arrangementincluding a pair of laterally spaced-apart screws 39extending throughthe top of the marginal flange 31 and the adjacent top flange structure33 and by a pair oflaterally spaced-apart screws 40 extending throughthe bottom of the boundary flange 38 and the horizontal flange 32. Thusit will be understood that the front panel 35 con-,

35 may be readily removed from the front wall 21 by removing the screws39 and 45.

The cabinet 2| houses a substantially vertically disposed vat 4|arranged in the upper portion thereof and offset toward the right closerto the side wall 25 than to the side wall 24. The vat 4| comprises topand bottom walls and 43, opposed side walls-44 and 45, and a rear wall46; the top and bottom walls 42 and 43 and the side walls 44 and 45terminate in a forwardly directed doorway 41 having a front opening 48arranged in substantial registry with the front openings 34and 36. Moreparticularly, the top and side portions or flanges of.v the doorway 41terminate in an outwardly and rearwardly rolled rim 49, while the bottomwall 43 is provided with a forwardly projecting flange 55 terminating inan,

upwardly and outwardly extending front ledge or lip 5| extending betweenthe side flanges of the doorway 41. The front ledge 5| is directed firstupwardly and outwardly and then downwardly terminating adjacent to thefront opening 48 of the doorway 41, whereby the upper edge of the frontledge 5| is disposed considerably above the bottom flange 50 andconsequently the bottom wall. 43. A substantially centrally disposeddownwardly depressed sump 52 is formed in thebottom wall 43 andcommunicates with a downwardly embossed depression or groove 53 formedsubstantially centrally in the bottom flange '50 and extending forwardlytoward the central portion of the front ledge 5|.

Further, an upstanding inverted substantially U-shaped inwardly embossedvat rib 54 is formed in the top wall 42 and'the side walls '44 and 45'flanges of the doorway 41. the vat rib 54.,-includ:-..

moval' of the vat 4| Withrespect to the cabinet- 2|. More particularly,a top tongue: 56; is secured to. the top central portion of the rollerrim 4!! and projects forwardly therefrom through. a top slot 5'| formedin thefront wall. 21 abovethe top of; the front opening 34; while twoside tongues; not shown, are respectively secured to the side. central.portions of the rolled rim49 and project forwardly therefrom through twoside slots; not shown, formed in the front wall 21 on oppositesides ofthe front opening 34. The rear wall 26 is provided with. forwardlydirected flange structure 58 defining an enlarged. opening 56 therein.through which the-vat 5!. may be readily inserted or removed withrespect to the cabinet 2|... Morespecifically, a first. rearwardlydirected fixture 66 is welded or otherwise secured mutually to the sideand rear walls 44 and 46 of the vat 4|; and a second rearwardly directedfixture BI is welded or otherwise secured mutually to the side and rearwalls 45 and 46. The two fixtures 60 and 6| are respectively secured tothe adjacent sides of the flange structure 58. by cooperating. bolts 62and 63, respectively, the bolts 62 and 63 being provided withassociatednuts as illustrated. Thus: it will be understood that the vat Al,together with its attachments subsequently described,,is'assembled as aunit and then inserted through the hole 59 in the rear wall 26 of thecabinet 2|, the tongues 56, etc., being slidably received in. thecooperating slots 51, etc and thereafter the fixtures 66 and 6| aresecured in place utilizing the bolts 62 and 63. Subsequently the frontpanel 35 may. be placed upon the-front wallZ] and secured inplaceemploying the screws. 39 and 40.

The cabinet 2| is provided with a front door 64.

that comprises an outer body sheet 65 terminating in an invertedsubstantially U-shaped rearwardly directed marginal flange 66, and aninner body sheet 67 terminating in an. inverted substantially U-shapedrearwardly directed marginal flange 68. The inner body sheet 6'!- isarranged in; nested relation within the outer body sheet 65 and suitablysecured in place so that the principal. portions of the body sheets 55and Glarearranged.

Further, the marginalflange 68 of theinner body sheet 6'! is provided with an outwardlydirected inverted substantially U-shaped marginal flange or lip 69 thatcooperates with the front surface of the associated vat rib 54 when the.door 64 oocupies its closed position. In order toretain the door 64 inits closed position a latch element 10 formed of a suitable moldedplastic, or the like, is secured to the central upper portion of themarginal flange 66 adjacent to the lip. 69 by an.

arrangement including a screw 1 The latch element 16 cooperates with aresilient corrosionresistant spring 12 secured within the upper centralportion of the doorway 41 by an arrangement including a plurality ofrivets 13; Also, the marginal flange 66. of the inner body sheet 61carries inverted substantially U-shaped rearwardly directed. bafilestructure 14 therein that projects adjacent to the vat rib 54 into theinterior of the vat 4| inorder to prevent the entry fwashing liquid intothe doorway 41. More particularly, the bafile structure; 14 carried; bythe marginal flange 68 of the inner body sheet 61 cooperates with.inwardly directed baflie structure formed inv the side walls and 45 ofthe. vat 4|. in orderto.

complete the gasketless vat and doorconstruction. The inwardly directedbafile structure formed in the left-hand sidewall 44 is indicatedgenerally at 15;. and the inwardly direetedbaflle structure formed inthe right-handsidewalli 45 is indicated generally at 76; these bafiiestructures l5 and 16 being: disposed'rearwardly of the upstanding legs55 off thevat rib. 54. Also, the left-hand sidewall 44 of the. vat 4|carries an inwardly directed embossed trackway indicated. generally at Hand the right-hand" side wall 45 of the vat. 4| carries an inwardlydirected embossed trackway indicated generally. at 18; the opposedtrackways Ti and 18 cooperating with and supporting movable dishcarrying rack structure generally indicated at 19.

The. door 645 is mounted: adjacent to the lower edge thereof withinlthedoorway 41 rearwardly of and below the front ledge 5| by a hinge ar--rangement including twolaterally disposed substantially identical hingemechanisms, whereby the lower ends of. the outer and innerbody sheetsand 61 are disposed in. straddling relationwith respect to thefront'ledgeilu More particularly, the right-hand hinge mechanism isindicated generally at 86 and comprises a first hinge element 8| securedto the flange 501 provided on thebottom wall 43 interiorly of the vat4ll and a.

second hinge element 82 secured to the front surface of the inner bodysheet 6| and disposed between the inner and outer body sheets 61 and 65.Also, this mechanism comprises a bumper space between the body sheets 61and. 65 and.

opening into the interior of the vat 4| for the purpose of receivingdetergent. Further, thev inner and outer body sheets 6'! and 65 arerestrained in spaced-apart relation by an upwardly and forwardlydirected laterally extending bracing sheet 66 secured to the frontsurface of the inner body sheet 61 andab-utting therear. surface of theouter bodyr sheet 65. Further thehinge mechanism 80. comprises a pintle.81 carried by the hinge element 8|, a cooperating. saddle 88 carried bythe hinge element 82,. and a locking pin 89 carried by the hinge element82 andcooperating with a locking slot 90 formed in the hinge element 8!.Further, a handle 91 is secured to the upper central front ofthe outerbody sheet 65 for the purpose of facilitating movement of the door 64between its open and closed positions; while the lower edge of the outerbody sheet 65 carries a laterally extending flange 92 that cooperateswith a' rearwardly directed ledge 93 formed on the front panel 35 justbelow the bottom of the front opening 36"formed' therein for the purposeof lending a finished appearance to the cabinet 2|: when the door. 64occupies its closed position. Finally, a door switch Hi4 is secured tothe front edge ofthezfront' ledge 5| and struction of the door 64, itwill be understood that the door 64 is movable into a closed positionwith respect to the doorway 41, at which time the outer body sheet 65occupies a substantially vertical position and is disposed substantiallyflush with the front surface of the front panel 35, and at which timethe inner body sheet 61 is disposed in an upwardly and forwardlyinclined position. The door 64 is restrained in its closed position bythe cooperation between the latch elements I and I2; whereby the bafilestructure I4 carried bythe marginal flange 68 of the inner body sheet6'I cooperates with the baffle structures i5. and I6 respectivelycarried by the side walls 44 and 45 and with the vat rib 54 carried bythe vat v4|, andthe lip 69 carried by the marginal flange 68 of theinner body sheet 61 engages the front surface of the vat rib 54; therebyto prevent the escape of washing liquid from the interior of the vat 4|into the doorway 47. Also, at this time the projection 95 carried by theouter body sheet 65 engages the plunger of the door switch 94, operatingthe door switch 04 to its closedcircuit position. Moreover, the door 64is movable into an openposition with respect to the door-way 41, atwhich time the inner body sheet 61 occupies a substantially horizontalposition and the outer body sheet 65 occupies an upwardly and forwardlyinclined position. Thus the door 64 is movable through an angle slightlyless than 90 degrees between its closed and open position. When the door64 is moved into its open position the projection 95 disengages theplunger of the door switch 94 operating the door switch 94 into itsopen-circuit position. Also, as the door 64 is moved into its final openposition the bumper member 84 carried bythe hinge element 32 engages thebumper member 03 in order rigidly to support the door 64 in its openposition; and the locking pin 89 carried by the hinge element 82 entersthe locking slot 90 provided in the hinge element 8| in order positivelyto prevent removal of the door 64 while it occupies its open position.At this time while the door 64 occupies its open position the dishsupporting structure I9 may be moved through the doorway 4? into and outof the vat 4|. More particularly, the rack structure I9 may be movedfrom a supported position upon the trackways TI and E8 within the vat 4|to a position exteriorly of the vat 4| upon the guide track 85, etc.,carried by the inner body sheet 67; whereupon dishes may bereadilyloaded or unloaded with respect to the rack structure I9. Thus itwill be understood that when the door64 occupies its open position itmay support the movable rack structure l9 permitting the ready placementand removal of dishes and other utensils with respect thereto.

In passing it is noted that when the door 64 occupies an intermediateposition with respect to its closed and open positions described above,it may be completely removed from the doorway 4i by virtue of the factthat the saddle 88 is disengageable with respect to the pintle 37 priorto entry of the locking pin 89 into the locking slot 90.

The general construction and arrangement of the door 64 and thecooperating baffle structures I4, I5 and I6 and the vat rib 54, as wellas the arrangement for movably supporting the rack structure I9 withinthe vat 4i and upon the door 64, have not been disclosed in great detailin the present application, since these arrangements formino partof thepresent invention, and are disclosed and claimed in the previouslymentioned Walker application.

Similarly, the construction and arrangement of the hinge mechanism 80has not been disclosed in great detail in the present application, sincethis arrangement forms no part of the present invention, and isdisclosed and claimed in the co=-pending application of Frank D. Low,Serial No. 61,633, filed November 23, 1948, now Patent No. 2,573,798.

The apparatus 20 further comprises an im peller I00 may be formed of anysuitable mate rial, such, for example, as Textolite and is mounted upona substantially vertically disposed operating shaft, not shown, of anelectric motor I62 arranged below the sump 52. More particularly, thesump 52 is provided with an upwardly directed emboss I03 that terminatesin a substantially vertically disposed tube, not shown,

through which the shaft of the motor I02 projects and which issurrounded by the hub of the impeller I00. The hub of the impeller I00may be secured to the shaft by an arrangement including a bolt I04extending through an opening provided therein, the inner end of the boltI04 being threaded into an opening provided in the upper end of theshaft of the motor I02. This arrangement permits ready rotation of theimpeller I00 by the motor I02 and prevents escape of any substantialamount of washing liquid from the vat 4I. The motor I02 is arranged in asubstantially vertical position and is provided with an upper end bellI05 that is secured to the lower surface of the sump 52 by anarrangement including two angularly spaced-apart brackets I06 eachhaving two downwardly directed legs receiving studs I01 carried by theend bell I05 and receiving cooperating nuts I08. Finally, an upstandingcylindrical reticulated screen I09 is removably arranged within the sump52 about the emboss I03 in surrounding relation with respect to theblades IOI of the impeller I00. The screen I00 serves as a strainer toprevent foreign articles suspended in the washing liquid contained inthe sump 52 from being caught by the blades IOI of the impeller I00 andflung upwardly through the dish supporting rack I9.

Provided in the space in the cabinet 2I below the vat M is a suitableliquid supply pipe III) which is adapted to be connected to a sourcepiped from the bottom of the cabinet 2! upwardly between the rear wall26 thereof and the rear wall 46 of the vat M by a flexible conduit I I Iand into the top wall 42 of the vat 4I. Specifically, arotary sprayingdevice II 2 is arranged within an upwardly extending emboss I I3 formedin the top wall 42 of the vat 4| so thatthe washing liquid may besprayed downwardly through the rack structure I9 carried within the vatM and allowed to accumulate in the sump 52. The liquid supply pipe H0 issuitably connected to an inlet valve mechanism II4 of the solenoiddashpot. type supported by the panel 32 and arranged to discharge intothe conduit II I. The inlet tothe conduit 1 II but is provided withan'asso- 'ciated solenoid H5 that is adapted when energizedto operatethe inlet valve mechanism I I4 *to its open position inorderthat'washingliquid may be supplied from the liquid supply'pipe I I viathe casing of the inletvalve mechanism N4, the conduit III and thespraying device I I2 into the upper portion of the vat 4|. Subsequently,when the solenoid H5 is de-energ'izedthe inlet valve mechanism 4 isreturned slowly to its closed position cutting off the communicationbetween the liquid supply pipe I I0 andthe spraying device I12. Theprovision of the slow-closing inlet valve mechanism'l I4 eliminateswater hammer in the plumbing preceding the liquidsupply pipe 0. Also, astrainer, not'shown, is incorporated inthe casing of theinlet valvemechanism -I I4 in order positively to prevent foreign material in theliquid supply pipe H0 from being conducted into the spraying device II2.

Also provided in the lower portion of thecab- 'inet 2| belowthe vat 4|is a drainpipe .I I6 that is .connected through a. suitable trap, i notshown, to a drain connection. The drainpipe H0 is carried by a fixtureII! that is, inturn, secured by a bolt M8 to a bracket IIBthat isweldedor otherwise securedto the exterior surfaceof the sump52. The drainfixture communicates with a flexible conduit that, in turn, communicates with admin fixture |2| thatis secured within a drain openingprovided in the lowermost portion of the sump 52.

52 and 'is restrainedin position "by an arrangement comprising astrainer I22 disposed in the throat thereof.

'The flexible hose I20 comprises a portion of'a drain mechanism I23 thatfurther includes structure I24 that is secured by a plurality "of screwsI25to a downwardly extending elementI2B welded, or otherwise secured, tothe side wall adjacent to thebottom'wall 43 ofthevat 4|. Alsolthe'structure l24'comprises a rearwardlyand upwardly extending arm I21carrying a resilient bumper I28 formed of rubber, or the like, and

arranged inengagement with the bottom wall 43 just above thesump 52.Further, the-structure I24 comprises'two spaced-apart guide elements I23 extending below the midsection of the hose I20; and a substantiallyS-shaped operating member|30 disposed between the guide elements I29.The operating member I30 i pivotally mounted adjacent to the innerendthereofupon a-pivot pin I'3I carried by the structure I24 and isnormallybiased in the clockwise direction, as viewed in Fig. 1, by acoil spring I32surrounding the pivot pin |3| and extending between thestructure I24 and the operating member I 30.

The extreme outer end of the operating member I30 carries an upwardlyextending-projection I33 underhooking the midsection of thehose "I 20and disposed between the outer surface of the 'hose 120 and theadjacentside'wallfl of'the cabinet 2|. Finally, 'thestructure "I 24carries an electroresponsive solenoid device I334 that is "provided witha movable armature |35which is 'oneratively connected by a coil springI36 to "the extreme inner end of the operating member I30.

In view of ".thBTOIBEOiIlg "it will'be understood that the hose I2 0extends in an 'arc'between" the tion thereofistnormally disposed *below'the drain opening provided in the sum 52 :so thatthe drain fixtures HIand 'IIl :arein free communication with eadhotherthroughthe hose I20,whereby any washing liquidin*thesump52may be-readily drained throughthedrain fixtures I21 and 'II'l by "way of the communicating ghose I 20.andinto the drainpipe I It. "Moreover, the operating member I30 isnormally biased *by the'weight of the hose "I 20 and against thecounter-balancing spring I32 in "the counterclockwise direction, "asviewediin'Fig. 1 ,-in order .to insure that the midsection of'the hoseI20 is moved intoits lower position :normally to rest :upon the curvedguide elements I 2 9.

When the solenoid I34 is energized the armaiture I35 is attractedrotating through the coil spring 13612118 operating member I30 in theclockwise direction, as viewed inFig. 1, about the pivot j pin 3| with'thebias of the coil spring I32 sothat the operating member I30 lifts orelevates the "midsection of the hose I20 from its lower position to itsupper position. J'More specifically, when-the solenoid I34 is thusenergized the oper- "ating'member I30 moves the midsection of the hoseI20to its'upper position disposed above the drain opening Provided inthe sump "52 effecting operation of the drain mechanism "I23 fromitsnon-draining positioninto its draining position. "Subsequent1y,when.thesolenoid I34 "is de-energizedthe weight of the "hose I20 returns the op-.erating :member :in "the counterclockwise direction, as'viewedin Fig.1,back into its normal position so that the midsection of the hose.Il'20fis returned toiits'lower position in order again to ,returnthedrainm'echanism from its non-drain- ,ling positioninto fits drainingposition.

Mounted within the lower portion of the vat 4| above the bottom wall 43and below the mov- :able rack structure 19 and surrounding the impeller10.0 is a suitable electric heater I31 which (is preferably of thesheathed resistance conductor-type; whichheater I3! is employed for thepurpose of drying dishes after they have'been washed and rinsedasexplained more fully hereinafter. The oppositeterminal ends of theheater'I 3l extend throuehliqtiid-tight openings provided in the :bottom wall43 to the exterior so that electrical connectionsmay b made thereto:from theexterior of the vat 4|. Also, a timer, not shown, is arrangedinthe upper portion of the space disposed between the left-hand sidewall "24 of the cabinet 2| and the left-hand .side wall 4! of the vat"4|; which timeriis provided withanio erating-shaft,:not shown, thatextends through-aligned opening provided in itheifront wall'zl and in'th iront'pan'el 35,.the extreme outer'end of the operating shaftremovablyoarrying a .control knob 1138.

. Considering now the general operation of the apparatus 20, when it isat rest, the control knob .I38 occupies the position illustrated in Fig.1,

whereby the index pointer I registers with the legend Off carried by theplate I39. At this time all of the electric circuits are open and thedoor 64 may be moved from its closed position into its open position,whereby the person may move the rack structure I9 from its retractedposition supported within the vat 4| into its extended positionsupported over the door 56. The dishes are then loaded into the rackstructure I9 andthe rack structure I9 is returned into its retractedposition within the vat 4|. At this time a suitable quantity of anappropriate detergent, such, for example, as that sold under the nameCalgonite is placed in the detergent cup, not shown, carried by theinner body sheet 61 of the door 64 and the door E lis then returned fromits open position into its closed position. The person then rotates thecontrol .knob I38 from its off position into its on position, wherebyoperation of the timer, not shown, is initiated. Also, operation of themotor I02 is initiated and the solenoid H5 is energized in order toeffect opening of the inlet valve mechanism H4. The washing liquid fromthe liquid supply pipe H0 is supplied to the spraying device H2 and issprayed thereby downwardly through the rack structure I9 in the vat 4Iac- ,ing liquid accumulating in the sump 52 is caught by the blades IOIof the impeller I00 and is flung upwardly and outwardly with arotarymotion in the counterclockwise direction, as viewed in Fig.4,through the rack structure .19. and is returned into the sump 52. When apredetermined quantity of washing liquid is supplied into the vat 4| acorresponding predetermined load is imposed upon the impeller I00 andconsequently upon the motor I02, whereby. the measuring coil, not shown,effects de- :12 energization of the solenoid I I5 so that theinlet valvemechanism II4 is returned to its closed position. Accordingly, ameasured quantity of washing liquid is supplied to the vat 4|. Also, thetimer is arranged to de-energize the solenoid H5 approximately 45seconds after the drain mechanism I23 is operated to its non-drainingposition in order positively to insure that the supply of washing liquidto the vat III is cutoff in the event of improper operation of themeasuring coil.

The first washing step described above continues for a total time ofapproximately 330 seconds following the closure of the drain mechanismI23, and within this time interval and in response to the accumulationof a predetermined quantity of washing liquid in the sump 52 the chargeof detergent contained in the detergent cup, not shown, is introduced orWashed into the washing liquid contained in the vat t I. Thisintroduction of the detergent into the washing liquid is accomplishedshortly following the operation of the drain mechanism :23 into itsnondraining position so that the detergent is present in the washingliquid during a substantial part of the time .interval of the firstWashing step. In passing it is noted that the detergent Calgonitecomprises about 40 per cent sodium hexametaphosphate and 60 per centsodium metasilicate.

At the conclusion of the first washing step the solenoid I30 isde-energized, whereby the drain mechanism I23 is returned to itsdraining position permitting the Washing liquid and the suspendeddetergent to be drained from the sump 52 into the drainpipe II'B. Inorder to insure that the hose I20 is not blocked by a partial air lockdue to the presence of air bubbles therein the fixture II'I carries anupstanding breather tube I4I communicating with the exterior, all asdescribed in the previously mentioned Stoddard application.

The washing liquid contained in the sump 52 is drained therefrom in avery short interval of 7 time; and approximately 45 seconds after thedrain mechanism I23 is operated into its draining position the solenoidH5 is energized in order to effect operation of the inlet valvemechanism H4 into its open position in order to initiate a second spraystep. The second spray step is then followed by a second washing step.in a manner substantially identical to that described above; andthereafter first and second rinsing steps are carried out in a similarmanner. Each of the rinsing steps proceeds for a time interval ofapproximately seconds and thereafter the drain mechanism I23 is againoperated into its draining position to insure draining of all of theWashing liquid from the sump 52.

At this time while the inlet valve mechanism II I occupies its closedposition and the drain mechanism I23 occupies its draining position, thetimer effects energization of the heater I31 while the motor I 02 isoperating in order to initiate a drying step. This drying stepproceeds-for a timev interval of approximately 1200 seconds, whereby theheat developed by the heater I31 effects drying of the dishes supportedby the rack structure IS, the hot air being circulated in the vat 4| bythe impeller I00. At

.the expiration of the time interval mentioned,

the timer opens the circuit of the motor I02 while continuing the supplyof electric energy to the heater I31 for a time interval ofapproximately 600 seconds in order to insure the furstructure 19. Atthis'time the timer has rotated the control knob I38tinzthe clockwisedirection,

as viewed 'in Fig. 1, from its on position back into its off position,whereby the circuit .for supplying electric energy to the heater I31 15interrupted. .At this time all of the electriccircuits are open and thewashing-cycle ha'sibeen completed. Thus the apparatus 20 :isautomatically operated through its various 1 spraying, washing, rinsingand dryingsteps as a consequence of the initiation ofoperation thereofby rotating the control knob 138 from itsoff position into itsom-position.

During operation of the apparatus 2D-through thetimedcycleabovedescrib'ed, thedoor'M must "be retained in its closed positionin "order toretain the door switch-94 in its'closedposition sincethedoor switch 94 is arranged as an interlock switch -in=theelectriccircuits. 'During the vari ous washing and rinsing steps whenconsiderable washing liquid is accumulated in the sump 52, it isnotedthatthe reticulated screen I09 prevents large particles of foreignmatter, such, forexample, as lettuce leaves, or the like, fromioeingcaught-in the blades I III of the' impeller I and flung upwardly andoutwardly thereby into the .rackstruc'ture i9 an'd the dishessupportedthere- 'by. At the conclusion of the timed cycle, the dishessupported by'the rack structure I9 have not only-been thoroughly washedandrinsed'but they have also been dried. Subsequently, the door 64 maybe moved from its closed position into its "open positionand-the rackstructure 19 may then be moved from :its retracted position within thevat 4| into its-extended position over the door 5 1 in order to permitremoval of the dishes therefrom.

Considering now in greater'detail the'improved construction of'the door64- and,more particularly, the upper portion thereof, and referring moreparticularly to Figs.2, 3, '4, 10, 1 1 and 12, it will be observedthatthe top portion of the marginal "flangefit of the outer=body sheet65 has acentrally disposed downwardly directed depression 7 I50 formedtherein that terminates in a cut out "or opening 'I5 I. The-depression150constitutes=a basin extending laterally across the *top of themarginal flange I66 and receives and supports vapor directing structureI52. As best shownin Figs. .10, 11 and 12,1the vapor directing structure.I'52 is substantially rectangular in plan and is "preferably integrallymoldedof a suitable plastic materialof low thermal conductivity.'The'structure I52 comprisesa dished body sheet 153 terminating in aboundary flange "including front andside portions I54andlI55, theboundary flange being substantially U-shaped. Also a plurality offorwardly and upwardlyclirectedand laterally extending louvers I56 areformed in the body sheet I53 providing correspondinglouver pen- 'ings,and a row of forwardly and downwardly :extending pins I 51 are formed.integrally with the front portion of'the body sheet just below the"front portion I54 of the boundary flange. "I-he 1 central-rearportionof the body sheet l 53 has an opening'or slot I58 formedthereinthatisadapted to embrace the latchlelement .III that islsecure'd to the topof the marginal flange 68 of the inner body sheet 61 .bythe screw I.previously 'described. Finally, a number of holes I 59 are formed inthe bodysheet I53 for :the purpose @of receiving .00-

1I'5'2 is arrangedin the depression 150 :formed in 1,5 M3 and I5'I*andscrews I60 previously mentioned. More particularly, thelaterallyspaced-apart pins I51 project 'through cooperating laterally:spacedapartholes IBI formed in the top-of the'marginal flange 66 whilethe screws I60 extend :through the holes I59 and are threaded intoopenings provided in the top I of the :marginal flange '68 of theinn'erbody sheet 61. .Also, two rows of laterally spaced-apart openings I62are-formedin-the top of the marginal flange 68 of "the inner body sheet61 so that the interiorof the door and, consequently,the interior o'fthe vat4 I communicates throug'h'the louvers I56 with the space disposedbetween the top of the marginal flange 66 of the outer :body sheet andthe top of the doorway 41, and thence withrthe exterior. 'Finally,theflange structure I4 arranged within'the marginal flange 68 of the rinner 'body sheet :81 carries .a "laterally :extending *and forwardlydirected shield :I63 underlying the openings :I62 formed in *thetop ofthemarginal flange 68 0f the inner body. sheet 61.

Referring now-more particularly to Figs. 2, 3 and 4, it will beunderstood that during 'the operation of the apparatus 20 whenthehot'washing liquid is contained in the vat 4|, moist -vapor therefromwill rise-towardthe upper portion of the vat 41 when the door64 occupiesits closed position. This vapor in the upper portion offthe vat 4| isvented between'the "top of the marginal flange 68 of the-inner bodysheet '61 and theshield I63 and thence through theholes I62andis'directed forwardly by the "louvers "I56 carriedby the structureI52 into the spacebetweenthe top of the marginaliflange 66 of theouterbodysheet 65 and the top of the doorway 41, whereby this vaporisdirected forwardlyout of the top of the front opening 36 when the door64 occupies its closed position. It will be understood that the shieldI63 also prevents hot washing liquid circulated in the vat 4| from beingdirected into the openings I62 and from escaping out of the top of thedoorway 41 when the door 64 occupies its closed position.

Also, it will beunderstood that since the door 64 and the vat 4Icooperate without the utilization of a gasket, some minor quantities ofvapor may escape from the upper portion of the vat 4| directlybetweenthe baffle structure "14 and the vatrib 54 and proceed'betweenthe front surface of the vat rib 54 and the abutting surface of theflange 'orlip "69 carried by the marginal flange68 of the inner-bodysheet 67. This'last-mentioned vapor proceeds into the space between thetop of the doorway 41 and the structure I52 and is directed forwardlyalong with the vapor passing through the louvers .I 56 out of the top ofthe front opening 36 when the door 64 occupies its closed position.

Referring now to Figs. '1, 2,3, 7, 8zand 9, it will be observed that thefront surface of the front panel 35 carries a laterally extending andforwardly directed vapor director IIlldisposed above the topof the frontopeningSB. As best shown in Figs. 7, 8 and 9, the vapor director I10 issubstantially triangular in section and colnprises'a .trimelement I'I-Iformed of metal and a bodyelement 12that ispreferablylintegrally moldedof .a suitable plastic materialof low thermal conductivity. The trimelement IJyI is preferablygiven ta finished and :polished coating ofchromium, a or the like, andcomprisesiailaterally extendingz bo'dy asubstantially icentrally :disposed for :a-esrrcar wardlyextending hood.I14, the hood I14 embracing the central portion of the body element I12.

A number of metal pins I15 are molded into the Further, the body .Asbest shown in Figs. 2 and 3, after the ele- -ments HI and I12 ofthevapor director E16 have been assembled, they are secured to the frontsurface of the front panel 35 above the top of the 1 front opening 35utilizing the rearwardly directed -pins-I15. More specifical1y,thelaterally spaced pins I15 project through and frictionally engagecorresponding laterally spaced-apart holes E18 formed in the frontsurface of the front panel 35. Further, metal spring clips or anchors,not shown,

may be secured to the ends of the pins I15 in engagement with the innersurface of the front panel 35 adjacent to the holes 6 18. As illustratedin Figs. 1, 2 and 3, a centrally disposed notch or recess I19 is formedin the lower portion of the front panel 35 just above the top of thefront opening 36 in order to accommodate the lower portion of the bodyelement E12 of the vapor di- .rector I16.

When thevapor director I16 is assembled as illustrated in Fig. 3 uponthe front surface of the front panel 35 above the top of thefrontopening 36 therear portion of the lower surface 516 of the body elementI12 projects rearwardly into the top front edge of the rolled rim 19disposed about the front opening 58 in the doorway 41, whereby theextreme lower rear end of the lower surface 816 of the body element I12overhangs the depression I50 formed in the top of the marginal flange 66of the outer body sheet 65 of the door 56 and conseouently the vapordirecting structure I52 when the door 64 occupies its closed position.

Again considering the operation of the appa ratus 26, it is pointed outthat the vapor which is directed forwardly by the vapor directingstructure,l52 out of the top of the front opening 35 is further guidedand directed by the vapor director I16 forwardly of the front surface ofthe front panel 35 into the kitchen or other room in which the apparatus25' is located. This cooperation between the vapor directing structureE52 and the vapor director I1!) is very advantageous as it prevents thevapor directed out of the top of the front 'opening 36 from risinggently into contact with ,the front edge of a supporting surface such,for example, as a sink, or the like, indicated at I86 in Fig. 3.

front edge of the sink I86 is normally quite cold, any vapor striking itwould condense and the resulting condensate would drip back upon thefloor -of'the kitchen; however, the vapor director I16 "prevents thisundesirable possibility since it proects the vapor forwardly from thefront surface of the front panel 35 beyond the front edge of the sinkI80. installed below the sink I86 the vapor issuing from the top of thefront opening 36 provided in the front panel 35 is projected by thevapor director I forwardly into the kitchen and rises -outwardly beyondthe front edge of the cold sink Accordingly, when the apparatus 25 is "Ipreventing undesirable condensation thereon.

. The formation of the vapor directing structure I52 and the vapordirector I16 of plastic material having a low thermal conductivity, isvery advantageous in view of the fact that it minimizes condensation ofthe vapor passing into contact therewith. Moreover, any small amount ofthe vapor that is condensed upon the lower surface I16 of the vapordirector Illlis guided by the serrations I11 rearwardly toward the lowerportion thereof and drips therefrom into or onto the vapor directingstructure I52. The serrations I11 are closely spaced to prevent theformation of large droplets of condensate falling therefrom upon thevapor directing structure I52.

Also, as best shown in Figs. 3, l0 and 12, two laterally extendinggrooves I54a are formed in the vapor directing structure I52 adjacent tothe front portion I54 of the boundary flange provided thereon for thepurpose of catching or trapping any condensate that might otherwise Ifall upon the floor of the kitchen when the door 64 is moved into itsopen position. The condensate accumulating on the structure I52 withinthe basin I50 formed in the top of the marginal flange 65 of the outerbody sheet 65 of the door 64, runs back through the louvers I56 onto theshield I63 and thence upon the inner body .sheet 61 and back into thesump 52 since the lower end of the inner body sheet 61 is disposedrearwardly of the front ledge 5| when the door 65 occupies its closedposition. The condensate runs down the rear surface of the inner bodysheet 61 into the groove or depression 53 and is returned to the sump52. Any of the vapor rising between the inner and outer body sheets 61 vand 65 and condensing thereupon, is deflected behind the front ledge 5Iand returned to the sump 52, the bracing sheet 86 extending between thebody sheets 61 and 65 insuring that any condensate running down theinner surface of the outer body sheet 65 is deflected rearwardly ontothe outer surface of the inner body sheet 61 and returned downwardlytherefrom behind the front ledge 5!. Also, a small amount of thecondensateaccumulating in the depression or basin I55 runs between thetop marginal flange 66 of the outer body sheet 65 and the cooperatingmarginal flange 68 of the inner body sheet 61 since the jointtherebetween is not liquid-tight, whereby this condensate runs down theouter surface of the inner body sheet 61 and isultimately deflectedrearwardly by the bracing sheet 86 in order to insure that it isreturned to the sump 52 rearwardly of the front ledge 5!.

Also, it is preferable that the handle 9| be integrally molded of asuitable plastic material having a low thermal conductivity in orderfurther to minimize condensation of the vapor passing thereover out ofthe top of the front opening 36. As illustrated in Fig. 3, the top ofthe handle SM is disposed substantially flush with the top of themarginal flange 65 of the outer body sheet 65 of the door 65 and belowthe lower surface I16 of the vapor director I15 when the door 64oocupies its closed position. Also, a number of laterally spaced-apartopenings 9Ia are formed. in the top of the handle Si in order to permitair to rise therethrough as a result of the forward projection of thevapor out of the top of the front opening 36, thereby further tending tominimize any condensation of the vapor upon the handle 9|.

As best shown in Figs. 4, 5 and 6, a' pair of condensate deflectinggaskets I8I are secured to the side flanges of the doorway 41 andcooperable with a pair of condensate deflecting gaskets I82 secured tothe sides of the marginal flange 66 of the outer body sheet 65 of thedoor 64; the pair of gaskets I 8| being disposed above the pair ofgaskets I82 and in engaging relation therewith when the door 64 occupiesits closed position. The gaskets I8I and I82 are disposed above thefront ledge I adjacent to the bottom of the door 64 and projectoutwardly terminating adjacent to the front surface of the front panel35. The gaskets I8I and I82 are sloped downwardly away from the frontopening 36 and extend rearwardly well behind the front ledge 5I.Preferably each of the gaskets I8I is integrally molded of rubber, orthe like, and is provided with an integral tab or bead I83 that projectsthrough and is frictionally retained in place in a corresponding slotI84 formed in the side flange of the doorway 41; and preferably each ofthe gaskets I82 is integrally molded of rubber, or the like, and isprovided with an integral tab or bead I85 that projects through and isfrictionally retained in place in a corresponding slot I86 formed in theside of the marginal flange 56 of the outer body sheet 65. Thisarrangement positively insures that any condensate draining down thesides of the marginal flange 56 of the outer body sheet 65 or down theside flanges of the doorway 41 when the door 54 occupies its closedposition, is caught by the gaskets I8I and I82 in engagement with eachother and deflected rearwardly behind the front ledge 5! and returnedvia the groove 53 into the sump 52.

In view of the foregoing, it will be understood that the dishwashingapparatus 20 is of the front-opening gasketless-door type and that thestructures I52 and I 10 cooperate in order to ventilate the interior ofthe vat M and to permit the escape of vapor therefrom while positivelypreventing this vapor issuing from the top of the front opening 36 fromcontacting the front edge of the cold sink I80 disposed above theapparatus 20 in order to prevent undesired condensation of the vaporthereon.

A modified form of the dishwashing apparatus 200 is illustrated in Figs.13 to 15, inclusive, that utilizes an air blast arrangement in ordertoassist in the ventilation of the vat and the projection of theresulting vapo outwardly from the top of the cabinet front opening. Theapparatus 200 is essentially of the construction of the apparatus 20disclosed in Figs, 1 to 12, inclusive, and comprises a cabinet 20E, afront panel 202, afront door 203, and a vat 204 arranged in the mannerpreviously described. The door 203 is arranged in the doorway 205provided in the front of the vat 204 and cooperates with a front opening206 provided in the front panel 202. The front surface of the frontpanel 202 carries the vapor deflector 201 positioned above the top ofthe front opening 206, and the top of the marginal flange of the outerbody sheet of the door 203 carries the vapor deflecting structure 283 inaccordance with the construction previously described. In thisembodiment the sump 209 of the vat 204 carries therebelow a combinationelectric motor and fan unit 2H3. More particularly, the unit 2I0 is ofthe totally enclosed type comprising a lower motor casing 2I I and anupper fan casing 2I2. An armature 2I3 is arranged in the motor casing 2|I and is carried by an operating shaft 2 I4 su1tably journalled therein,the operating shaft 2I4 projecting through the fan casing 2I2 andcarrying the impeller 2ll'i disposed within the sump 209.

Also, fan blade structure 2I6 is arranged within the fan casing 2I2 anddirectly secured to the shaft 2I4. Finally, the motor casing 2II isprovided with an air intake fixture 2 I1, and the fan casing 2I2 isprovided with an air discharge fixture 2I9. Preferably, the air intakefixture 2I1 comprises filter structure 220, and the ai dischargeconnection 2I9 comprises a threaded union 22 I.

The motor and fan unit 2 I0 is of a well-known type and is arranged whenoperated to draw air through the filter structure 220 into the intakefixture 2 I1 and thence into the motor casing 2| I. The air in the motorcasing 2I I effects cooling of the electrical elements of the electricmotor and is conducted into the fan casing 2I 2 wherein it is compressedand discharged under positive pressure through the discharge fixture 2I9into the threaded union 22 I. Thus the air effects cooling of theelectric motor and is preheated and discharged under positive pressureinto the union 22 I. Of course, that shaft 2 I4 of the electric motornot only operates the impeller 2I5 disposed within the sump 209, but italso operates the fan blade structure 2I6 to effect compression of theair in the fan chamber 2I2 and the consequent discharge of the air underpositive pressure into the union 22 I.

Also, in this embodiment the top of the vat rib 230 disposed between thebody of the vat 204 and the doorway 205 comprises a wall of a conduit23I and, more particularly, a sheet 232 is extended over the top of thevat rib 230 and the sides thereof are suitably welded in place in orderto define the other wall of the conduit 23I. Accordingly, the conduit23I extends laterally across the top of the vat rib 230, and theright-hand side thereof terminates in a flanged coupling 233 that issecured to a cooperating flanged coupling 234 carried by the upper endof a pipe 235, the lower end of the pipe 235 being suitably threaded andsecured to the union 22I. The pipe 235 extends between the union HI andthe flange coupling 233 at the right-hand end of the conduit 23 I,whereby the air discharged from the discharge fixture 2!!! is conductedvia the union 22I, the pipe 235 and the flanges 234 and 233 intotheconduit 23I under positive pressure. Physically the pipe 235 isarranged between the right-hand side wall of the vat 204 and theright-hand side wall of the cabinet 20I.

A first series of longitudinal spaced-apart holes 24I are formed in thebottom wall of the conduit HI and communicate with the interior of thevat 204; and a second series of laterally spaced-apart holes 242 areformed in the front wall of the conduit 23I above the upper end ofthe'flange or lip carried on the rear end of the marginal flange of theinner body sheet of the door 203 and communicate with the space betweenthe top of the doorway 205 and the vapor directing structure 208.

In view of the foregoing, it will be understood that when the apparatus200 is operating, the preheated air is delivered from the fan casing 2I2into the conduit 23I under positive pressure and is projected throughthe two series of holes MI and 242. The preheated air projected throughthe series of holes 24I enters the interior of the vat 20I causing aslight positive pressure therein, whereby the vapor is readily forcedthrough the vapor directing structure 208 into the space disposedbetween the structure 208 and the top of the doorway 205, Also, thepreheated air projected through the series of holes242 sweeps for,-

19 wardly directly through the space disposed between the structure 268and the top of the doorway 205 in order positively to insure that thevapor is projected forwardly out of the top of the front Opening 2% whenthe door 263 occupies it closed position.

In passing it is noted that the two series of holes 24! and 242 arereally alternative and that an air blast operation of the apparatus 26!!is obtained utilizing only one of these series of holes, although thetwo series of holes may be utilized in combination very advantageously.First assuming that only the holes 265 are provided, it will beappreciated that the pressure of the air in the vat 29 2 will beadequate in order to force the vapor through the structure 263 when thedoor 203 occupies' its closed position. Now assuming that only the holes242 are provided, it will be appreciated that the pressure of the air inthe space between the structure 208 and the top of the doorway 2%produces a Venturi action, whereby the air sweeping over the structure288 causes the vapor to be drawn therethrough from the interior of thevat 284,

In any case the air from the conduit 23l effects projection of the vaporout of the top of the front opening 266 under positive pressure, wherebythe forwardly projecting air carrying the vapor renders unnecessary thevapor director 201. While the vapor director 2011 is really not requiredin this air blast embodiment of the apparatus Zllil, as noted above, itis very useful in defining the forwardly directed passage through whichthe air is projected and itv does further positively prevent any of thevapor from contacting the front edge of a sink disposed above theapparatus Zilll.

In view of the foregoing, it will be understood that the dishwashingapparatus 280 is of the front-opening gasketless-door type incorporatingan improved air blast arrangement for ventilating the interior of thevat and for positively preventing the vapor issuing from the. frontopening of the cabinet of the apparatus from contacting a cold worksurface such, for example,

as a sink, or the like, when the apparatus is employed in combinationtherewith and disposed therebelow.
